Carboniferous Period and Insect Evolution

The video explores the Carboniferous period, a time over 300 million years ago when Earth was dominated by giant insects due to high oxygen levels. It discusses the formation of Pangea, the lush climate, and the eventual transition to an ice house Earth. The video highlights the role of oxygen in insect gigantism and the impact of climate change on ecosystems. It concludes with a call to action for environmental conservation.
